I have a fescue lawn w/ clay soil and want to install an irrigation system. The picture is my house with the proposed rotor placement. My turf is already very thick and dense so the irrigation will be used only a few times a year during drought (1 once a week max). The back is layed out with minimal heads and the front it textbook. I'm looking for input on the head placement mainly in the back. Will this work? If not, why? The front seems like overkill. Can I do the front like the back and remove heads? The areas not covered will have spray heads (not shown).
